Pick rates of season 10 in my version:
Octane - suits everyone: newbs, ppl who want to have "fun", hackers, players who value mobility, players who abuse how fast game renders fast movement, etc.
Wraith - mostly bad, ones that are good just have 5000+h in this game and they are actually able to be good with any legend, mainly Ego players who don't care that only they can go into the void most of the time
Blood - easy wallhack till Seer came about, able to track easy kills = solo players, helps teammates with the aim and game sense via scans = you just see, don't need to think or listen to audio
Path - a mix between Octane and Wraith
Valk - for people who don't want to think about rotations and pros/hackers who like to drop on ppl
Lifeline - same as Wraith just worse
Loba - for ppl who likes to die with the best loot in the game, mostly.
Bangalore - Shiv fans and ppl who have not realized that her smoke is useless since it was f-up in season 9, helps a lot to people who can't dodge well (e.g. myself)
Horizon - used to be easy, now similar as Wraith case
Caustic - new meta for camping
Fuse - for ppl who just like to have fun and engage in fights from a distance
Mirage - I still think that data is fake or comes from the public only where ppl are fooled by his abilities, in ranked he is just useless
Seer - took the part of Blood's players while being overpowered, not anymore, R.I.P.
Gibi - can't believe he is that low, probably all coming from ranked as people in public can't play him and he is useless with randoms who just leave you to die in your bubble trying to pull out 1vs3
Rev - used to be useless, now Octains best friend.
Wattson - same as Wraith and Horizon
Rampart - now you see how much mobile Sheila is worth
Crypto - no one can play him well except pros
p.s. I personally use Octane, Path and Valk in ranked when playing with randoms - so I always have a way out, can run away when they f-up badly and at least can have a chance ratting till the end.
